Diagnostic Current Sources
To detect a connection failure to an external sensor, the ADuC7060
incorporates a 50 μA constant current source on the selected
analog input channels to both the primary and auxiliary ADCs.
Reference Sources
Both the primary and secondary ADCs have the option of using
the internal reference voltage or one of two external differential
reference sources. The first external reference is applied to the
VREF+/VREF? pins. The second external reference is applied
to the ADC4/EXT_REF2IN+ and ADC5/EXT_REF2IN? pins.
By default, each ADC uses the internal 1.2 V reference source.
For details on how to configure the external reference source for
The diagnostic current sources for the primary ADC analog
inputs are controlled by the ADC0DIAG[1:0] bits in the
ADC0CON register.
Similarly, the diagnostic current sources for the auxiliary ADC
analog inputs are controlled by the ADC1DIAG[1:0] bits in the
ADC0CON register.
